I mean in all actuality it hasn't been THAT long since Johnny stepped down. I was 12. Do you think they watch it because of the longevity or because they truly think Leno is funny? IMO Letterman used to get more laughs outta me.
I watch it for headlines Monday and when they have animals on or when an interesting guest is on.
Leno will be retiring in 2009 and they will be giving Conan his spot.
